TheTravel.com did a series on the top 10, and I'm sharing them again here. BTW, cemeteries aren't haunted. Earth bound ghosts who chose to stay, stay at places they knew in life, a place where they died, lived or liked. However, spirits who have crossed over can come back and visit living people in cemeteries. Now, on to the bizarre cemetery of the day...
Old Jewish Cemetery, Czech RepublicThis crammed Jewish cemetery in Prague is dated to at least the 15th Century, and was accepting new burials until the late 18th Century — that's a lot of burials. Its headstones are tilting, crumbling, and lopsided, having endured centuries of new burials.
It's estimated that up to 100,000 individuals are buried within the tiny cemetery, though only 12,000 headstones remain. Since Jewish tradition forbids the replacement of graves, the dead were stacked on top of one another. The cemetery sits about 10-feet above the street as a result of the stacked burials.
